reduce, reuse, recycle
When the climate is warming what is this called?
global warming/ climate change
Where does geothermal energy come from?
heat deep within Earth's core
What is pollution?

A country near the equator gets sunlight most days of the year. Explain why solar energy would produce a large amount of electricity there.
Solar energy would produce a large amount of electricity there because the area gets a lot of sunlight, and more sunlight allows solar panels to generate more energy.
Why is conservation important for the future?
Conservation is important because it helps save resources so people in the future will still have energy, water, and clean air.
What happens when too much CO₂ is in the atmosphere?
global warming, climate change, etc
Explain why fossil fuels are nonrenewable.
Fossil fuels are nonrenewable because they take millions of years to form and we use them faster than they can be replaced.
Give two environmental problems caused by fossil fuels.
Air pollution, Global warming, Climate change, Oil spills, Water pollution, Rising Sea Levels, etc
A country with many volcanoes wants renewable energy. Which energy source should they use?
geothermal energy
Which is better long-term: renewable or nonrenewable energy? Explain why.
Renewable energy is better long-term because it does not run out and causes less pollution.
What human activities raise global temperatures?
deforestation, burning fossil fuels, etc
